$7000 is compounded semiannually at a rate of 11% for 21years Find the total amount and round to the nearest cent
photoshop1234 [79]

\text{Given that }\$7000 \text{ is compounded semiannualy at a rate of }11\% \text{ for 21 years}\\&#10;\\&#10;\text{we know that the amount after t year when compounded is given by}\\&#10;\\&#10;A=P\left ( 1+\frac{r}{n} \right )^{nt}\\&#10;\\&#10;\text{here P is the principal amoount, so }P=7000,\\&#10;\\&#10;\text{r is the interest rate, }r=11\%=0.11\\&#10;\\&#10;\text{n is the number of times in a year, here semiannulay, so }n=2,\\&#10;\\&#10;\text{and t is the time, so }t=21\\&#10;\\&#10;\text{so the amount after 21 years is}

A=7000\left ( 1+\frac{0.11}{2} \right )^{2(21)}\\&#10;\\&#10;\Rightarrow A=7000\left ( 1+0.055 \right )^{42}\\&#10;\\&#10;\Rightarrow A=7000\left ( 1.055 \right )^{42}\\&#10;\\&#10;\Rightarrow A\approx 66328.68

So the amount after 21 years is: $66328.68

Divide 30 by it's half, add the half of 18 that has been divided by the half of the half of 12 after been divided by half.
WARRIOR [948]

Answer:

We want to divide 30 by it's half.

The half of 30 is 30/2 = 15

then we have: 30/15 = 2

Now we want to add the half of 18, that has ben divided by the half of the half of 12 hafter been divided by half.

The half of 12 is 12/2 =  6

the half of the half of 12 is 6/2 = 3

now, we wanto to divide the half of 18 by that number.

The half of 18 is 18/2 = 9

then we have 9/3 = 3

and we wanted to add this to the number previous found:

2 + 3 = 5

36 + 64 = c^2
100 = c^2
√100 = c
10 = c
